In this blog post, we’ll provide a detailed analysis of a malicious payload we’ve dubbed “Impala Stealer”, a custom crypto stealer which was used as the payload for the NuGet malicious packages campaign we’ve exposed in our previous post. The sophisticated campaign targeted.NET developers via NuGet malicious packages, and the JFrog Security team was able to detect and report it as part of our regular activity of exposing supply chain attacks.

Are you or your development team tired of using application security tools that generate countless results, making it difficult to identify which vulnerabilities pose actual risks? Do you struggle with inefficient or incorrect prioritization due to a lack of context? What adds insult to injury is that traditional CVSS scoring methods ignore critical details like software configurations and security mechanisms.

Malicious packages are often spread by the open source NPM and PyPI package repositories, with few other repositories affected. Specifically – there was no public evidence of severe malicious activity in the NuGet repository other than spam packages used for spreading phishing links. As with other repositories, the JFrog Security Research team regularly monitors the NuGet repository for malicious packages, including manual analysis of suspicious code.

The recent OpenSSH double-free vulnerability – CVE-2023-25136, created a lot of interest and confusion regarding OpenSSH’s custom security mechanisms – Sandbox and Privilege Separation. Until now, both of these security mechanisms were somewhat unnoticed and only partially documented. The double-free vulnerability raised interest for those who were affected and those controlling servers that use OpenSSH.

Announcing the general availability of JFrog Xray’s advanced security features in self-hosted subscriptions, organizations have the flexibility to manage and secure their software development pipelines in-house and in the cloud.
